Bacteria
1. Staphylococcus epidermidis – Common skin bacterium, breaks down sweat/oils into pungent fatty acids.
2. Corynebacterium spp. – Known for creating cheesy, rancid odors (often linked to foot odor in humans too).
3. Brevibacterium linens – Famous for its “stinky cheese” smell; also produces sulfur compounds.
4. Proteus mirabilis – Breaks down amino acids into foul-smelling sulfur compounds.
5. Pseudomonas aeruginosa – Can give off a “sweet, popcorn-like” odor due to volatile compounds.
Fungi
1. Candida albicans – A yeast that thrives in damp, warm areas; produces sour, musty odors.
2. Trichophyton mentagrophytes – A dermatophyte fungus linked to athlete’s foot; makes sweaty feet smell worse.
3. Aspergillus niger – Common mold that gives off earthy, stale odors.
4. Penicillium spp. – Can contribute a musty, spoiled smell if present on skin or bedding.
A sugar glider’s feet have an unpleasant scent reminiscent of stale popcorn.
The distinct odor appears as a yellow hue.
